SHUTTER REGULATOR FOR MOVING-PICTURE MACHINES.

Application filed February 23, 1921.

To all whom it may concern:

Be it known that I, FRED Y. .loonNnAY. a citizen of the United States, residinq at Orange, in the count of Orange and t tate of Texas. have invented certain new and useful Improvements in Shutter Regulators for Moving-Picture Machines; and I do hereby declare the following to be a full,

clear. and exact description of the invention. such will enable others skilled in the art to which it appertains to make and use the san1e.

The invention relates to cinematographic apparatus and more particularly to the shutter mechanism of moving picture machines. adjusted with ease and convenience and made secure in the located position.

Other objects and advantages will be ap-. parent and suggest themselves as the nature of the invention is understood.

\Vhile the drawings illustrate an embodiment'ofthe invention, it is to be understood that in adapting the same to meet different conditions and requirements. various changes in the form, proportion and minor details of construction may be resorted to without departing from thenature of the invention.

Referring to the accompanyingdrawings forming a part of the specification.

Figure 1 is a side view of a shutter mechanism for moving picture machines emhod ving the invention,

Figure 2 is a central longitudinal section,

Figure 3 is a cross section on the line 3-3 of Figure 1.

Figure 4 is a transverse section on the line li of Figure 1, and

Figure 5 is a detail view of the shutter supporting member and parts associated therewith.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings h v like reference characters.

The numeral 1 designates a. hearing such as usually provided in moving picture Inachinery for supporting a shaft 12. A. guide 3 is connected to the hearing 1 by means of straps 2 and receives a feed screw 1-. An annularly grooved nut 5 mounted on the feed screw 8 has a swivel joint connection with the guide 3 by means of a screw 6 threaded into the guide 3 and entering the annular groove. of the nut 5. A. hand wheel 7 is associated with the nut 5 and may form a part ope-rating Serial No. 447,204.

thereof and provides means for conveniently the nut when effecting adjustment of the shutter. The feed screw 8 is provided in a side with a longitudinal groove 8 to receive the inner end of a screw t which is threaded into the guide 3. This prevents rotation of the feed? screw and provides means for securing the same in the required adjusted position.

A sleeve 13 is mounted loosely on the shaft 12 and a head or enlargement thereof is formed with an annular groove 11 which receives the bifurcated end of a. fork 10 secured to the feed screw 8 by means of a s rew 9. The sleeve 13 has a longitudinal slot 27 in a side thereof and is formed upon its exterior with a spiral or helical groove 14. The sleeve 13 is free to move longitudinally on the shaft 12 but is prevented from rotation thereon. A collar 16 is loosely mounted upon the sleeve 13 and has adjustahle connection with the shaft 12 by'means of a set screw 15; The set screw 15 is threaded into the collar 16 and passes through the slot 27 of the sleeve 13 and its inner end is adapted to engage one of ralitv of notches 25 formed in the length of the shaft 12. It will thus be understood that the screw 15 performs the double office of securing the collar 16 in the required adjusted position as well as preventing rotation of the sleeve 13 on the shaft 12. The collar 16 has an annular groove 26.

A sleeve 17 is mounted on the collar 16 and has a swivel joint connection therewith. Set screws 18 threaded into opposite portions of the sleeve l7ienter the annular groove 26 of the collar 16 and prevent relative longitudinal movement of the two parts, while admitting of free rotation of the sleeve 17 An out/er flange 30 is formed at one end of the sleeve 17 and receives a. stud 20 which forms the connecting means between the sleeve 17 and the shutter 22. The shutter 22 is loose on the sleeve 17 and its central portion is provided with a plurality of openngs 24 to coact with the stud 2 to secure the shutter in the relative ad justed position. A washer 19 is mounted on the sleeve 17 and is retained in place thereon hy the projecting ends of the set screws 19- An expansihle helical spring 31 mounted on the sleeve 1? is confined between the washer 19 and the shutter 22 and vieldablv holds the latter in engagement with the flange 30. The. side of the washer 19 facing the shut- [or is recessed to receive the spring- .ll. A projection 23 upon the inner side of the sleeve l7 enters the spiral groove 14 and effects rotation of the sleeve l7 and shutter 22 when a longitudinal movement is imparted to the sleeve 1.3.

l'Vhen the parts are assembled, they orcupy the relative positions substantially as indicated most clearly in Figures 1 and 2. The collar 16 and parts connected therewith may be adjusted to any pointin the length of. the sleeve 13 andare made secure in the located positions by means of the screw 15 engaging any one of the openings 25 in a manner herein before stated. Quick adjustment of the shutter may be effected by movement ithereof against the tension of the spring 21 to clear the stud 20. After the shutter has thus been adjusted, it is returned to normal position against the flange 30 through the action of the spring 21, thereby causing the stud 20 to enter one of the openings 24 registering therewith. Further-adjusment of the shutter 22 is ef fected by rotation of the nut5, the screws 4: and G bein-g previously loosened. Rotation of the nut .5 effects longitudinal adjustment of the screw 8 and the sleeve 13 connected therewith. Longitudinal movement of the sleeve 13 effects rotation of the shutter 22 by reason of the helical connection between thesleeves l3 and 1?. The direction of rotation of the shutter will depend upon thedireetion of movement of the sleeve 13, as will be readily understood. After the shutter has been adjusted, it is made secure by retightening .the screws 4and 6 in a manner well understood.

What is claimed is z,

1. In shutter mechanism of the character specified, a shaft,,a longitudinally movable sleeve mounted .on the shaft and provided in a side with a longitudinal slot, a collar mounted on the sleeve, connecting means between the collar and shaft and passing through the slot of the sleeve, a rotatable sleeve having a swivel joint connection with the collar and having helical connection with the longitudinally movable'sleeve, and a shutter oarriedby the rotatable sleeve.

2. In shutter-mechanism of the character specified, a shaft, a longitudinally movable sleeve mounted on the shaft and provided in -a side with alongitudinal slot, a collar adjustable on the sleeve, means l'or seruriin; the collar to the shaft in the adjusted position and passing through the longitudinal slot of the sleeve, a rotatable sleeve having a swivel joint connection with the collar and a helical connection with the longitudinally movable sleeve, and a shutter carried by the rotatable sleeve.

3. Shutter adjusting mechanism of the character specified comprising a shaft, a longitudinally movable sleeve on-the shaft and having a slot in a side thereof, a collar on the longitudinally movable sleeve, connecting means between the collar and shaft and paming through the slot of the longitudinally movable sleeve, a rotatable sleeve having swivel joint connection with the col= lar' and having a helical connection with the longitudinally movable sleeve, a shutter adjustable on the rotatablesleeve, and a spring between the shutter and rotatable sleeve to hold the shutter in relative adjusted positron.

, 4. Shutter mechanism of the character specified comprising a support, a guide mounted on the support, a feed screw in the guide, a nut carried by the guide for adjusting the feed screw, a shaft carried by said support, a longitudinally movable sleeve on the shaft, conneotiong means between the feed screw and sleeve, a collar on the longitudinally movable sleeve, connecting means between the collar and shaft and passing through a slot in a side of the longitudinally movable sleeve, a rotatable sleeve hav' ing a swivel joint connection with the collar and formed with an outstanding flange and having a helical connection with the longitudinally movable sleeve, a shutter loose on the rotatable sleeve and having a plurality of circularly arranged openings, a stud can rird by the rotatble sleeve and adapted to engage any one of .the said openings, a washer on the rotatable sleeve, and an expansible helical spring between the washer and shutter for normally holding the latter in open position.

In testimony whereof I aflix my signature in presence of two witnesses.
